CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No.61/150,802 filed on Feb. 9, 2009 and entitled Method and a system forcontrolling and tracking radiation emitted from mobile phones, which isincorporated in its entirety herein by reference.

BACKGROUND OF THE INVENTION

Cellular communication is based on transmission of RF signals betweenmobile phones or handsets and a cellular base station. The user of themobile phone is exposed to non ionizing radiation emitted from themobile phone. Radiation is known to decease as a factor of square of thedistance from the radiation source.

During recent years increasing scientific evidence has indicated thatlong term exposure to non-ionizing radiation may cause potential damageto human tissues.

The emitted radiation, which is the power transmitted from the mobilephone to the base station is not constant over time and is beingadjusted constantly due to environmental conditions such as distance,obstructions surrounding buildings and terrain. The absorbed radiation,which is the amount of radiation absorbed by the human tissue, may be afunction of the emitted radiation, the distance between the handset andthe tissue the specific physiology of the user and other parameters.

The rate of radiation absorption per mass of tissue, often referred toas Specific Absorption Rate (SAR) may be a factor of the emitted handsetradiation, the distance between the mobile handset and the user, thephysiology of the user and other parameters. Specifications of themaximum allowed SAR for a specific handset are found in, for example,the Federal Communication Commission, Evaluating compliance with FCCguidelines for human exposure to radiofrequency electromagnetic fields,Supplement C (edition 01-01) to OET bulletin 65 (edition 97-01), FCC,2001.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT INVENTION

In the following detailed description, numerous specific details are setforth in order to provide a thorough understanding of the invention.However, it will be understood by those skilled in the art that thepresent invention may be practiced without these specific details. Inother instances, well-known methods, procedures, and components have notbeen described in detail so as not to obscure the present invention.

The term “plurality” may be used throughout the specification todescribe two or more components, devices, elements, parameters and thelike.

According to embodiments of the invention, the radiation absorbed permass of tissue of a user (hereafter “absorbed radiation”) is estimated.The absorbed radiation may be presented to the user on the handset, to auser of peer handset which is a handset with which the conversation isbeing held, or to a user of a monitoring handset which is a handsetdefined and configured to supervise mobile handset. The absorbedradiation data may be sent over the cellular network and a communicationnetwork such as the internet to a server or a personal computer (PC). Inaddition, a user may be given various recommendations aiming atdecreasing the amount of the absorbed radiation. Various actions may betaken if the absorbed radiation exceeds a predefined threshold. Forexample, the conversation may be disconnected, an alarm may beactivated, a massage may be sent to a peer or a monitoring handset, orother suitable actions may be taken. Statistics of the absorbedradiation and potential absorbed radiation over time may be presented tothe user on his hand set, on a user personal computer (PC) and the like.

According to embodiments of the invention, decreasing the absorbedradiation may be achieved by decreasing the emitted radiation or byincreasing the distance between the mobile handset and the user or both.

According to embodiments of the invention, the absorbed radiation may beestimated during a call. Additionally or alternatively, a prediction ofthe absorbed radiation level (hereinafter “predicted absorbedradiation”) may be estimated and given to the user while the handset isnot engaged in a call. The predicted absorbed radiation is an estimationof the radiation that would have been absorbed by the user, had the userbeen engaged in a call in the time the prediction is being made.According to embodiments of the invention, given an estimation of themass of the user head, it is possible to calculate the radiationabsorption for the head, by multiplying SAR the estimated mass of thehead.

According to embodiments of the invention, the value of the absorbedradiation may be estimated and presented to the user together with anestimation of the potential absorbed radiation. The potential absorbedradiation is the level of radiation that would have been absorbed by theuser, if the user was holding the handset close to his head or bodywhile in a call. Moving the mobile handset away from the head and bodyof the user may result in a significant decease in the absorbedradiation levels. In this case the potential absorbed radiation may behigher than the absorbed radiation level. Presenting to the user thepotential absorbed radiation together with the absorbed radiation, orthe differences between the potential absorbed radiation and theabsorbed radiation, may give the user an estimation of the decrease inthe amount of absorbed radiation caused solely by removing the mobilehandset away from his head or body.

According to embodiments of the invention, the estimated amount ofabsorbed radiation may be presented. For example, the amount of absorbedradiation for a specific call may be presented to the user. SAR may beestimated and presented. SAR may be presented over different time unitssuch as seconds, minutes, hours, days, months etc.

Reference is now made to FIG. 1 which is a schematic illustration of ageneral architecture of a system 10 according to embodiments of theinvention. According to embodiments of the invention, mobile handset 110may be in active communication with cellular network 170 and maycomprise a radio frequency (RF) unit 120 and an antenna 130 for thereception and transmission of RF signals, a core logic unit 142comprising of a radiation estimation unit 140, and action generationunit 150, and handset extra modules unit 160 comprising functionalityunits such as Bluetooth unit 162, proximity sensor 163, vibrator 164,encoders/decoders (CODECS) unit 165, display 166, location basedservices (LBS) unit 167, speaker 168, temperature sensor unit (169),accelerometer (171), and magnetometer (172). A wired headset 173 may beconnected to handset 110, or alternatively, handset 110 may be in activecommunication with a wireless headset 174. For example, handset 110 maybe in active communication with a wireless headset 174 using Bluetoothprotocol utilizing Bluetooth unit 162. Core Logic unit 142 maycommunicate over one or more communication mediums such as cellularnetwork 170 or the Internet (not shown) with various entities such asone or more servers 180 connected to said handset via a network, such ascellular network 170 or the internet (not shown), a peer mobile handset185, which is a handset with which a conversation is being held, amonitoring mobile handset 190 which is a handset defined and configuredto supervise mobile handset 110, and a user PC 195. According toembodiments of the invention, core logic unit 142 may communicate withthese entities additionally or alternatively using other means ofcommunication. For example, core logic unit 142 may communicate withuser PC 195 using one or more protocols for exchanging data over shortdistances, such as Bluetooth wireless communication (not shown), aUniversal Serial Bus (USB) (not shown) cable and the like.

According to embodiments of the invention, radiation estimation unit 140may estimate the absorbed radiation. Action generation unit 150 mayreceive absorbed radiation estimations from radiation estimation unit140. Action generation unit 150 may be pre-configured or configured by auser of mobile handset 110 locally through input and output means ofmobile handset 110 or remotely through user PC 195, via monitoringhandset 190, or via server on the internet 180, for example, via aservice provider server on the internet (not shown). User PC 195 can beused for modifying configurations of mobile handset 110 via a server ordirectly to a single or multiple handsets. Action generation unit 150may initiate one or more of various actions based on the absorbedradiation estimations and on the action generation unit 150configuration.

According to embodiments of the invention, radiation estimation unit 140may estimate the SAR, the total amount of absorbed radiation duringcalls or over time. These estimations may relate to the actual absorbedradiation by the user. Additionally, radiation estimation unit 140 mayestimate the potential absorbed radiation. In addition, radiationestimation unit 140 may give a prediction of the absorbed radiationwhile the handset is not engaged in a call.

It will be noted that although a communication session enabling two ormore humans or other entities (e.g., a human caller and a server) tocommunicate over a cellular network will typically be referred tohereinafter as a call, the term “call” should be expansively and broadlyconstrued to include any applicable session or interaction carried overa cellular network. A call may be a telephony session, an instantmassaging session, a video session, a chat session, a web browsingsession or any other applicable type of multi-media interaction.

According to embodiments of the invention, action generation unit 150may be configured to perform one or more of the actions listed belowupon, or in response to the occurrence of one or more of the followingevents: when absorbed radiation exceeds a predefined thresholdmomentarily or over a predefined time duration, or if the accumulatedabsorbed radiation estimation reaches a predefined threshold:

Alert the user. The user may be alerted by an audio indication, a visualindication, by vibration of the handset (using vibrator 164) and thelike, or any combination thereof.

Disconnect a call to prevent undesired exposure to RF radiation. It ispossible, however, that certain calls would not be disconnected if thepeer mobile handset 185 is included in a predefined priority list.

Direct a call to a wired headset 173 or wireless headset 174 ifavailable, or else to speaker 168.

Inform the event to the user of peer mobile handset 185. The user ofpeer mobile handset 185 may be informed by a massage such as textmassage using Short Message Service (SMS), an audio indication, a visualindication, by vibration of the handset and the like, or any combinationthereof, as may be applicable.

Inform the event to the user of monitoring mobile handset 190. The userof monitoring mobile handset 190 may be informed by a text massage(SMS), an audio indication, a visual indication, by vibration of thehandset and the like, or any combination thereof, as may be applicable.

Give various recommendations to the user aiming at decreasing the amountof the absorbed radiation. These recommendations may be given as visualand/or audio indications.

According to embodiments of the invention a recommendation given to theuser may include for example, a guidance indicator to direct the usertowards a cellular base-station the user communicates with, in order todecrease the distance or align to a line of sight between the user andthe cellular base-station. As the radiation level decrease with thesquare of the distance from the radiating source, getting closer to thebase-station may increase the received power proportional to the squareof the distance, under various conditions, for example, in case thereexists a line of sight between the handset and the base station. As thereceived power increases, the output emitted radiation of the handsetdecreases. Therefore, it is expected that getting nearer to thebase-station in case there is a line of sight between the handset andthe base station may result in decrease of handset 110 emitted radiationand, therefore, in a decrease in the absorbed radiation.

Another recommendation may be, for example, to move to a better locationwhere the mobile handset will radiate less power, or move to a previouslocation where the mobile handset radiated less, both may result in lessabsorbed radiation to the user. According to embodiments of theinvention action generation unit 150 may keep a record of estimatedabsorbed radiation values and their respective coordinates in variouslocations. Getting the location coordinates of handset 110 may beachieved by using, for example, LBS unit 167. Action generation unit 150may base the recommendation to move to a previous location where themobile handset radiated less on this record of estimated absorbedradiation values and their respective location coordinates. The user maybe directed to a previous location where the mobile handset radiatedless using the readings of magnetometer 172.

Another recommendation may be, for example, “switch to vertical phoneposture” or “switch to horizontal phone posture”. Action generation unit150 may get readings from an accelerometer of the handset, if available,and determine the posture of the handset based on these readings.Switching to an alternate phone posture may reduce emitted radiation,and therefore, absorbed radiation, since in many handsets the antenna isdesigned to have best reception and transmission characteristics in aspecific position. If any of wired 173 or wireless headset 174, isavailable, a recommendation to switch to wired 173 or wireless headset174 may be given. Switching to wired 173 or wireless headset 174 andmoving the mobile handset away from the user's head and body maydecrease absorbed radiation levels. Additional recommendations may be,for example, use loudspeaker.

According to embodiments of the invention, action generation unit 150may compare and present to the user values of estimated or predictedabsorbed radiation levels, while handset 110 communicates throughseveral cellular networks of various service providers. In case the usermay choose among various service providers, the user may consider theabsorbed radiation levels while making his choice. Action generationunit 150 may recommend the user of the service provider with which thelowest emitted radiation and hence the lowest absorbed radiation levelswere achieved.

According to embodiments of the invention a radiation report summarizingabsorbed radiation values may be given to the user of handset 110, theuser of monitoring mobile handset 190, or to any other predefined party.The report may include tables, graphs or other forms of datarepresentation that may indicate momentarily absorbed radiation levels,such as peak absorbed radiation levels and the like, accumulatedabsorbed radiation levels over various time intervals such as day, week,month and the like.

Reference is now made to FIG. 2 which is a schematic illustration of agraphical representation of estimated potential absorbed radiation 210and estimated absorbed radiation level 220 according to embodiments ofthe invention.

According to embodiments of the invention various data items may betransmitted to server 180, for example to a service provider server onthe web. These data items may include, for example but not limited to,received power per time, estimated absorbed radiation, peripherals usedby the user (e.g. wireless headset 174, wired headset 173, and speaker168) and location. These data items may be used by different entitiesfor various purposes. For example, the service provider may use thisaccumulated data from handset users for different purposes, such asimprovements/optimization of the network coverage, etc. Network coveragerefers to the geographical region within which the handset can reliablyreceive and transmit signals to and from the network.

According to embodiments of the invention, a server application may usethese data items to create regional maps of cellular network coverageand quality by accumulating multiple inputs from a plurality ofindividual mobile handsets. The regional maps may be presented to theuser on the mobile handset, or on the server 180. The regional maps mayinclude, for example but not limited to, the following data: absorbedradiation estimation per location, received power per location, andaccessories (wireless headset 174, wired headset 173, and speaker 168etc.) used by different users per location.

Reference is now made to FIG. 3 which presents a schematic flowchartillustration of a method of controlling and tracking absorbed radiationfrom mobile handsets according to embodiments of the invention.According to embodiments of the invention, a handset may be firstconfigured (block 310) to present absorbed radiation estimations and toperform actions as desired by the user. While not engaged in a call,prediction of absorbed radiation may be presented to the user (block315). The Prediction of absorbed radiation may be presentedcontinuously, or per the user request. After a call starts (block 320),absorbed radiation may be estimated (block 330). Estimated data may bepresented to the user (block 350) during the call and action may beperformed (block 340) according to absorbed radiation levels andaccording to the handset configuration. The levels of absorbed radiationmay change following the action generated at block 340. For example theabsorbed radiation may change if the conversation is disconnected, ifthe user moves to a different location, if the user begins to speak witha wired or wireless headset and moves the handset away from his headetc. Therefore, the process of estimating absorbed radiation (block330), presenting data (block 350) and performing action (block 340) maybe repeated as needed, continuously or intermittently providing feedbackto the user. In case the user moves the handset away from his head thevalue of the potential absorbed radiation may be estimated and presentedas well. After the call ends (block 360), a summary of absorbedradiation estimations and potential absorbed radiation may be presentedto the user (block 370) according to the handset configuration.

Reference is now made to FIG. 4 which present schematic flowchartillustration of method of estimation of absorbed radiation according toembodiments of the invention. According to embodiments of the invention,estimation of absorbed radiation levels may be divided into two phases,as presented in FIG. 4. Phase 1 may be a preliminary phase performed inthe laboratory, preferably for each of the handset models for whichradiation estimation is intended to be done. In phase 1 variousreal-life scenarios may be simulated (block 410) using specializedequipment as known in the art. The simulated testing real-life scenariosmay include using the handset in urban areas, in rural areas, whilemoving in different speeds, including effects of multipath and fading aswell as other testing scenarios. During simulation, absorbed radiationis measured and may further be recorded (block 414) together withvarious handset parameters (block 412), as will be explained in moredetails below. The measured absorbed radiation recordings may be timesynchronized with the handset parameters recordings. Then, an empiricalformula associating the measured absorbed radiation with the recordedhandset parameters may be fitted (block 416). The empirical formula maybe a combination of logarithms, polynomials and other mathematicalexpressions, taking into consideration the different cellulartechnologies of, for example, the second (2G), third (3G) or othergenerations, that may minimize the prediction error of absorbedradiation or get it below a desired threshold. The empirical formula ofblock 416 may be used for estimating absorbed radiation while thehandset is engaged in a call.

The absorbed radiation and SAR measurements setup used for estimation ofabsorbed radiation according to embodiments of the invention is known inthe art and described, for example, in IEEE 1528, “Recommended Practicefor Determining the Peak Spatial-Average Specific Absorption Rate (SAR)in the Human Head from Wireless Communications Devices MeasurementTechniques” or in Supplement C (Edition 01-01) to OET Bulletin 65(Edition 97-01), “Additional Information for Evaluating Compliance ofMobile and Portable Devices with FCC Limits for Human Exposure toRadiofrequency Emissions” (June 2001).

According to embodiments of the invention, a combination of thefollowing handset parameters may be used for the estimation of theabsorbed radiation: received signal code power (RSCP), energy perchip/noise EC/IO, Downlink Frequency, Uplink Frequency, Max TransmitPower, Transmit Power, received signal strength indication (RSSI), Band,absolute radio frequency channel number (ARFCN), C1, C2, Cell ID,discontinuous reception (DRX) and discontinuous Transmission (DTX),received signal (Rx) quality, serving and neighbor cell information.According to embodiments of the invention, a subgroup of theseparameters may be recorded. Additionally or alternatively, othersuitable parameters may be recorded and used

Additional parameters that may be used are the readings of theaccelerometer, magnetometer, the battery charging status and temperaturesensor of the handset, if available. The reading of the temperaturesensor may indicate the temperature of the battery of the handset. Thetemperature of the battery of the handset or the battery charging statusmay correlate with the transmission power. The readings from theproximity sensor of the handset may be used to determine whether thehandset is close to or far from the user, which may have an impact onthe absorbed radiation estimation. Additionally, the potential absorbedradiation may be the outcome of the formula of block 416 of FIG. 4,assuming that the reading from the proximity sensor of the handsetindicates that the handset is in close proximity to the user's head.

According to embodiments of the invention, in phase 2, the empiricalformula, generated for the handset model, is uploaded to a specifichandset (block 418), the relevant parameters are retrieved (block 420)and substituted in the empirical formula to get an estimation of currentabsorbed radiation (block 422). The method described in phase 2 of FIG.4 may be preformed while the handset is engaged in a call to receiveestimation of absorbed radiation. Alternatively, the method described inphase 2 of FIG. 4 may be preformed while the handset is not engaged in acall for predicting absorbed radiation.

It will be appreciated that other methods for getting emitted power andabsorbed radiation values are possible. For example, emitted radiationmay be directly measured using dedicated hardware, and a formularelating emitted radiation to absorbed radiation may be generated.

Some embodiments of the present invention may be implemented in softwarefor execution by a processor-based handset, for example, core logic unit142. For example, embodiments of the invention may be implemented incode and may be stored on a storage medium having stored thereoninstructions which can be used to program a system to perform theinstructions. The storage medium may include, but is not limited to, anytype of disk including floppy disks, optical disks, compact diskread-only memories (CD-ROMs), rewritable compact disk (CD-RW), andmagneto-optical disks, semiconductor devices such as read-only memories(ROMs), random access memories (RAMs), such as a dynamic RAM (DRAM),erasable programmable read-only memories (EPROMs), flash memories,electrically erasable programmable read-only memories (EEPROMs),magnetic or optical cards, or any type of media suitable for storingelectronic instructions, including programmable storage devices. Otherimplementations of embodiments of the invention may comprise dedicated,custom, custom made or off the shelf hardware, firmware or a combinationthereof.

Embodiments of the present invention may be realized by a handset thatmay include components such as, but not limited to, a plurality ofcentral processing units (CPU) or any other suitable multi-purpose orspecific processors or controllers, a plurality of input units, aplurality of output units, a plurality of memory units, and a pluralityof storage units. Such handset may additionally include other suitablehardware components and/or software components.
